The marketing firm Kirshenbaum Bond & Partners has leased 16,000 square feet at 10 Hudson Square, expanding its operations in an area increasingly defined by a presence of media firms.

Hudson Square, just west of SoHo, is dominated by the unlikely real estate giant Trinity Church, which owns six million square feet in the area, making it by far the most dominant landlord. Just in the past year or so, the neighborhood has seen the number of media-related firms flourish, attracting the likes of WNYC, New York magazine, Viacom, and CBS radio.

“It’s a neighborhood that’s earlier in its evolution than other more established areas, but it’s catching up fast,” the lead broker on the most recent deal, Daniel Horowitz, of brokerage Studley, said.

The Kirshenbaum Bond & Partners deal, also brokered by Peter Capuciati, David Providenti and Jon Rosenblatt of Studley, brings the marketing firm’s total space in Hudson Square to 68,000 square feet. Office rents in the area are around $50 a square foot.
